Part clamping mechanism and using method thereof

Abstract

The invention discloses a part clamping mechanism and a using method thereof. The clamping mechanism comprises a workbench, a cylinder and a flap seat, wherein the cylinder and the flap seat are arranged on the workbench; a connecting rod shaft is arranged in an inner hole of the flap seat and connected with the output shaft of the cylinder; the cylinder drives the connecting rod shaft to move inthe flap seat; the other end of the connecting rod shaft is connected with a clamping plate through a curved connecting rod; the curved connecting rod is fixed on the flap seat through a turnover shaft pin and drives the clamping plate to move vertically or rotate; the curved connecting rod is provided with a curved groove with a certain included angle, and the turnover shaft pin is positioned inthe curved groove; and the curved connecting rod moves in accordance with the curve of the curved groove in different direction by using the turnover shaft pin as a fixed point. The part clamping mechanism keeps the turnover form of a pressure head, ensures that a flap vertically clamps a part, prevents the pressure head from blocking the picking and placing of the part during moving, and meanwhile, ensures that the surface of the part is not scratched during clamping.

Description

technical field [0001] The invention relates to a part clamping mechanism and a using method thereof, in particular to a clamping mechanism for plastic shell parts such as automobile instruments and oil pumps. Background technique [0002] Some of the auto parts and components, such as auto instrumentation and oil pump, are plastic shell parts. During the production and testing process, the outer surface of these parts needs to be protected, and there should be no scratches or indentations. Housings are often precisely positioned and pneumatically clamped for assembly and inspection accuracy. [0003] The general production line equipment uses the cylinder to drive the lever to turn over and clamp the parts. The fundamental defect of this clamping method is: since the clamping point follows a circular arc curve at the head of the lever, it touches the surface of the part and continues to clamp The indenter will have a slight displacement on the surface of the part, and this...
